Fuel Pressure Check (1990-91)
- Depressurize fuel system. See DEPRESSURIZING PROCEDURE (1989-91) . Switch off ignition. Disconnect the battery negative lead.
- Connect the pressure gauge on the outlet from the filter, located on the chassis under the right rear wheel arch.
- Reconnect the battery and turn the ignition to II position, while observing pressure gauge. Pressure should be 34-38 psi (2.39-2.67 kg/cm2 ). Maximum allowable pressure drop is 10 psi (0.7 kg/cm2 ) per minute. If pressure is low, ensure filter is not blocked and pump is operating correctly, recheck pressure. If pressure is still low renew regulator. Repair or replace fuel pressure regulator as necessary.
